At OpenPrescribing we are piloting a number of data-driven approaches to identify unusual prescribing and collect feedback on this prescribing to inform
development of new tools to support prescribers and organisations to audit and review prescribing. These pilot results are provided for the interest of advanced users,
although we don't know how relevant they are in practice. There is substantial variation in prescribing behaviours, across various different areas of medicine.
Some variation can be explained by demographic changes, or local policies or guidelines, but much of the remaining variation is less easy to explain.
